Hello,
The last blocker for 1.36.0-wmf.29 is:
* MemcachedPeclBagOStuff: Serialization of 'Closure' is not allowed
- https://phabricator.wikimedia.org/T273242
It comes from the extension FeaturedFeeds which attempt to serialize
some User objects in the cache. An issue we already identified in a
previous train when we marked User as not being serializable:
https://phabricator.wikimedia.org/T264391
This time it is unknown what caused the regression (most probably it is
due to a change in mediawiki/core). Anyway there is a patch up for
review to stop serializing those objects but instead drop usage of User
objets and cache an array of properties instead of the object itself:
https://gerrit.wikimedia.org/r/c/mediawiki/extensions/FeaturedFeeds/+/661357/
Without this fixed, the train can not progress further.
cheers,
